Electrohydraulic control gearshift device for tractor

Abstract

The invention discloses an electrohydraulic control gearshift device for a tractor. The electrohydraulic control gearshift device for the tractor comprises a shifting fork and is simple in structure.The electrohydraulic control gearshift device for the tractor is applied to solving the executing part of gearshift. In China, tractors commonly use mechanical gearshift mechanisms. If power gearshiftmechanisms at abroad are used, the conventional tractor structure will lose the original characteristics, and high price tractors will bring huge using cost to national economy. The research key point is how to control the conventional tractors by means of comprehensive characteristics of machinery, electricity and hydraulicity to fully complement shortcomings of machinery, electricity and hydraulicity effectively. The device is a novel product researched without changing the structure of the conventional tractor. Conventional shifting fork, shifting fork shaft, lever and the like are replaced by the electrohydraulic control gearshift mechanism, so that power gearshift can be achieved. Tractors can be updated by additionally mounting data detection, operation and remote control units, sothat automation and intelligence are achieved.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an electro-hydraulic control shifting device for a tractor. Background technique [0002] At present, the shifting of tractors and construction machinery is generally controlled by mechanical force (manpower). Although some tractors and construction machinery use electro-hydraulic control, they are all realized by wet clutches or continuously variable transmissions. The structure is complex, costly, and cost-effective. These technologies come from developed countries. In the country, key components are heavily dependent on imports. my country has not yet made a real breakthrough in this field. The tractor and construction machinery industry has a certain gap with Western developed countries in terms of automation, intelligence, and humanization. How to realize the intelligence of various types of machinery and improve international competitiveness is our responsibility. To a...
